Java in browsers

How do i create a java application in a browser?
I know i can create an applet but I need only text ouput.
With applets i would need to tell the compiler the where i want to place my text with x, y coordinates
I want to create something like this: http://home.comcast.net/~fhcsmith/intro/ch2/ch2ex4.html
(Ignore everything else except the "Java Console I/O")

If I add a textarea I won't be able to do somethings like user inputHow about a text field and a "enter" button for input and a text area for output?
And by all means, switch from AWT to Swing. An applet's GUI can
be as complex as your imagination allows.

Help - I cannot set the Default Java for Browsers

Hello:
I'm running Win 7, the Home Premium, 64 bit flavor. I have IE 8 and FF 3.5.8 installed. FF is the default browser. I've installed Java and when I go to the test page: http://www.java.com/en/download/help/testvm.xml
I get a message which says: "Something is wrong. Java is not working."
HOWEVER, if I open a command prompt and type java -version, I get this:
C:\Users\dogzilla>java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode)
So I went to the control panel app, the advanced tab, and expanded the node for Default Java for Browsers. I have 2 problems.
1. The checkbox for Microsoft Internet Explorer is greyed out; I cannot change any settings here at all.
2. I checked the checkbox for Mozilla Family. Then, when I click OK, I get an error message which states:
"Unable to change browser settings. Please check that Mozilla or Firefox or Netscape is properly installed on the system and/or that you have sufficient permissions to change system settings."
Since I'm writing this message to the forum using FF, I'm going to guess that I have the browser installed correctly. So that leaves me with a permissions problem -- which I don't doubt. I have no idea where to start looking though. Especially considering I can run the files in the bin directory from a command line without any problems.
Does anyone know how I can solve the two problems I described in this thread? Suggestions are greatly appreciated.
Thanks!

Thanks for the reply!
I tried running as admin and no luck. Still experiencing the same problems.
I've did some more reading (much more in fact for what this problem should be worth) and other forums mention that on 64 bit Windows systems, both the 32 bit and 64 bit JRE need to be installed.
When I was running Win XP, I could just download the SDK, create an environment variable, and I was good to go. Now, it looks like if I just install the SDK, I need the JRE plugin download for just the browsers -- what a ridiculous waste/duplication!
Thanks again for your help.

Websites that use java are not working. In the Java control panel, under advanced, default java for browsers "mozilla family" won't stay clicked

I've recently gotten a new Windows 8 computer. Ever since, I've tried accessing certain websites (like www.cnet.com) and can't get the java scripts to load like for the drop down menus. When I hover over them they don't do anything. Other computers I have that run Windows 7 are working just fine.
I've upgraded Firefox and Java to all of the newest versions but it's still not working. When I go to the Java control panel, under "Advanced" and under "Default Java for browsers", the check box next to "Mozilla family" won't stay checked. I'll check it, click "Apply" and "Ok" and then when I open it back up it's unchecked again.
Help.

Script Default Java for browsers

Hello all,
I would like to know if is it possible to script the enabling of "Default Java for browsers". http://www.java.com/en/download/help/5000021500.xml
We have a large deployment of the JRE currently 1.6.0-05, we would like to run a script for all users to make sure that IE is enabled within the control panel for Java.
I have been unable to find a successful registry setting or file setting to enable this for all users. It appears that the setting is only enabled if done manually through the Java control panel.
Does anyone know how this can be scripted to enable for all users, we would like to do this on login through kix or group policy.
thanks for your help.

Java Enabled Browsers

Does OS 2.0 support Java Enabled Browsers. If so how do I down load this app

You'll need to have two separate pages or place the non-java navigation code between the applet tags. Think about all the poor people using Lynx that couldn't move on your site ...

Fedora 13: After upgrading from FF3.6 to FF6.0.2 I no longer have a Java plugin. How do I configure the Java Plugin for FF 6 ? There is no Java Plugin at the site

I am Fedora 13x64 bit. I just installed FF v6.0.2 from the FF download site. I backed up the existing FF 3.6 as firefox_old
I need to have a Java plugin to access company site, how do I configure the Java Plugin ?
At the Plugin area in FF6 there is no Java Plugin available, even after a search.
I have Java 1.6.0 installed in the OS at:
/usr/lib/jvm/java-1.6.0/jre/lib/amd64/libnpjp2.so
I googled how to configure Java Plugin for FF 6 for Fedora 13 and the trick was to create a soft link from /home/<userID>/.mozilla/plugins to the above libnpjp2.so

Web pages will not run correctly, says need Java- L505d-S6957

I have a new L505D-S6957 running the Windows 7 upgrade 32-bit. I have tried using Firefox and IE8. Both browsers seem to not run Java or not run correctly if so. Though when I check my Java it is latest and installed. Buttons on web pages and photos do not load or run. I have tried re-loading the Java, the browsers, and about anything else I can think of. Some web pages load jumbled as if without any margin.
Can anyone help me determine what is going on here? Some of my favorite web pages do not work and one will not even log me on. I could not log on to this website to get this help. It keeps returning back to the login screen after I try to login. However, I was able to login here on the first try on another computer. Thanks for any help on this matter.

Java not working even though it's enabled.

so... no sites are recognizing java (well, they recognize it but think it's disabled but trust me, it's not).
recently, i removed it then did a clean reinstall, including deleting some registry entries cuz it was stuck on saying something like "you already have this software installed on your computer. would you like to reinstall it?" and i got SICK OF IT BUT DOING IT DIDN'T DISABLE IT... did it? besides, 3rd party sites can't snoop around my registry.
thoughts?

1.6.0_15
i thought i found the culprit in that i went into the java console -> advanced -> default java for browsers -> "mozilla family" was unchecked, so i checked it but no matter how many times i do that, i go back there and it's UNCHECKED EVERY TIME.
what gives?

Java 7 update 10 not working with Internet Explorer 8

Hi there,
I recently upgraded to Java 7 update 10 and ever since no Java applet loads in Internet Explorer 8 (works fine in Firefox 17.1).
I've tried uninstalling Java and reinstalling Java many times, makes no difference.
Can someone help me please?
Thanks
Ninko
P.S. I'm running Windows Vista Home Premium (all updated), in case it helps.

I agree - check to make sure IE itself hasn't disabled Java.
Since you're using Java 7.10, please also check the Security tab in the Java Control Panel which can be found in the Windows Control Panel.
While in the Java Control Panel, check also the Advanced tab and make sure Microsoft Internet Explorer is checked under 'Default Java for browsers'
Alternatively check this registry key: HKCU\Software\AppDataLow\Software\JavaSoft\DeploymentProperties
For this setting: deployment.webjava.enabled
Make sure its set to 'true' to enable java; if its 'false' it disables java.

How to Force Internet Explorer specific Java Runtime Environment?

Problem: UConn uses a tool called Blackboard. Blackboard requires Version 1.5.0 (build 1.5.0_07-b03)
but I develop so NETBeans IDE needs/wants JDK6 ( likes JDK 6 Update 16 )
Tried managing add-ons in IE, Tried Firefox too.
What I want is to have IE forced to the JDK5 runtime and let my other applications (NetBeans, Oracle, OracleSQLDeveloper, Firefox and MYSQL use the JDK6). I know NEtBeans will allow to specify which JDK but it seems that IE still sees both and screws up.
Things I tried but didnt work: managing add-ons and I saw items like this Force Internet Explorer to use a specific Java Runtime Environment install?
from: http://stackoverflow.com/questions/71254/force-internet-explorer-to-use-a-specific-java-runtime-environment-install
First, disable the currently installed version of Java. To do this, go to Control Panel > Java > Advanced > Default Java for Browsers and uncheck Microsoft Internet Explorer.
Next, enable the version of Java you want to use instead. To do this, go to (for example) C:\Program Files\Java\jre1.5.0_15\bin (where jre1.5.0_15 is the version of Java you want to use), and run javacpl.exe. Go to Advanced > Default Java for Browsers and check Microsoft Internet Explorer.
To get your old version of Java back you need to reverse these steps.
Note that in older versions of Java, Default Java for Browsers is called <APPLET> Tag Support (but the effect is the same).
The good thing about this method is that it doesn't affect other browsers, and doesn't affect the default system JRE.
Any ideas?

Simple then - bad idea.
If your minimal target is 1.5 then you develop in 1.5. If you insist on using 1.6 for functional reasons then you will need to maintain two development environments on your box 1.5 and 1.6. You explicitly build support for 1.6 and detection for that into the code and test it using 1.6. And test using 1.5 as well.
Note you must test both 1.5 and 1.6. Full functional tests.
Obviously limiting yourself to 1.5 would require less effort (cost.)

My Applet not running in java not installed systems.

dear sir/madam,
i have an applet which uses java.awt.* and java.awt.event.* classes, is running in systems with J2SE installed. but it is not running in systems with java enabled browsers without J2SE installation.
i want my applet to be run in all java enabled browsers without J2SE also.
how to make my applet work.
thanks in advance.
-- ks_moses

install J2SE to develop Java programs..
install JRE to run your Java Programs
To run your applets into such a browser, you must have a plugin installed on that browser to run your applet, so install JRE(Java Runtime Environment), it will install the Java plugin automatically so you can run your applets, GoodLuck
Regards,
Mohammed Saleem

Trying to Write Files in Java

I've written this; it's one of three classes that work together in a java applet.
import java.applet.*; import java.awt.*; import java.util.*; import java.io.*;
class Game{Graphics run(Graphics bufferGraphics, ArrayList<Image> image, Buff buff){
//* Game Code *************************************************************************************************************************//
 bufferGraphics.drawImage(image.get(1),0,0,800,600,buff);
 bufferGraphics.drawImage(image.get(0),100,100,400,300,buff);
 File file = new File ("Meh.dat");
 try{
 PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(file)));
 out.close();
 catch(IOException ex)
 bufferGraphics.drawString("Error!", 0, 0);
return bufferGraphics;}}
//*************************************************************************************************************************************//If I take out
 try{
 PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(file)));
 out.close();
 catch(IOException ex)
 bufferGraphics.drawString("Error!", 0, 0);
 }It works fine, but with that in there, the other two classes don't work (And it doesn't even write the file). It doesn't even give me my error message, so I'm confused.
The I/O code works fine in a file with system.out.println, so I think it might have to do with the out method/class/whatever.

On that site, it says this:
Can applets read or write files?
In Java-enabled browsers, untrusted applets cannot
read or write files at all. By default, downloaded
applets are considered untrusted. There are two ways
for an applet to be considered trusted:
1. The applet is installed on the local hard disk,
in a directory on the CLASSPATH used by the program
that you are using to run the applet. Usually, this
is a Java-enabled browser, but it could be the
appletviewer, or other Java programs that know how
to load applets.
doesn't being in the same folder/server count as no.1?Yes but in that case you need a permissions file ... don't expect your users to have that or know how to do it. If this is yours and you are running it for yourself or someone you can give the permissions file to, then no you don't need to sign it - you just need to know how to do the grants. search this site for how to do that (tutorial/t-tip/already asked question ... )

Firefox won't accept java plugin

I need to get firefox to accept a java plugin to print to my dymo labeler in Amazon seller "scan and label"
Amazon support told me to download java 7 which I did and it did not work, then I was told to go into the java settings under the "Advanced" tab and enable "Mozilla family" for "Default java for browsers" Every time I try to do this this setting will not save and I think that the firefox browser is stopping it.
Amazon support also says that after doing this I should be able to go to firefox add-ins and I will see it under plugins and I cannot.
I think that firefox is blocking this. Is there a way to unblock this?
Using64 bit OS, windows 7 and and the latest firefox 30.0

The Java Runtime environment is deactivated so I can't play games on Yahoo; how to fix?

The Java Runtime environment can be downloaded at cnet dot com and at other websites. It is necessary to install the Java Runtime Environment in order to play games provided in the Yahoo Games area. It worked fine until I upgraded; now it won't work. Not sure how to enable it, that is, if it is possible to simply enable it.
